Other peripherals:
Up to 108 general-purpose I/O pins with programmable pull-up, pull-down, or bus
keeper.
Vectored Interrupt Controller (VIC) with 16 priority levels.
Up to 19 level-sensitive external interrupt pins, including CAN and LIN wake-up
features.
Configurable clock-out pin for driving external system clocks.
Processor wake-up from power-down via external interrupt pins; CAN or LIN activity.

40 C to +85 C ambient operating temperature range.
Two 10-bit ADCs, 8 channels each, with 3.3 V measurement range and conversion
times as low as 2.44 s per channel. Each channel provides a compare function to
minimize interrupts.
Multiple trigger-start option for all ADCs: timer, PWM, other ADC, and external
signal input.
Four 32-bit timers each containing four capture-and-compare registers linked to
I/Os.
Four six-channel PWMs (Pulse-Width Modulators) with capture and trap
functionality.
Two dedicated 32-bit timers to schedule and synchronize PWM and ADC.
Quadrature encoder interface that can monitor one external quadrature encoder.
32-bit watchdog with timer change protection, running on safe clock.
On-chip very low-power ring oscillator; fixed frequency of 0.4 MHz; always on to
provide a Safe_Clock source for system monitoring.
On-chip crystal oscillator with a recommended operating range from 10 MHz to
25 MHz. PLL input range 10 MHz to 25 MHz.
On-chip PLL allows CPU operation up to a maximum CPU rate of 125 MHz.
Generation of up to 11 base clocks.
Seven fractional dividers.
clock control of individual modules.
allows minimization of system operating power consumption in any configuration.
CPU operating voltage: 1.8 V
I/O operating voltage: 2.7 V to 3.6 V; inputs tolerant up to 5.5 V.
